MACHINE FO'R SEWING ON BUTTONS.

SPECIFIQATIQN forming part of Letters Patent No. 643,614, date Application filed November 6,

To a/ZZ whom/it may concern:

Be it known that we, ALBERT O. 'lowNs, residing at Hudson, in the county of Hillsborough and State of New Hampshire, and j FRANK W. LYNDE, residing at Melrose, in Il through which the n to the county of Middlesex and State of Massachusetts, citizens of the United States, have invented a new and useful Improvement in Machines for Sewing on Buttons, of which ro'the following is a full, clear, and exact description, reference being had to the accompanyingdra\vings,forming a partof this speciiication, in explaining its nature. The invention-relates to a machine for sewing on -buttons having the features herein- Y after described.

In the drawings,Fignre 1 is a view,partly inside elevationand partly in section, of a machine containing the features of our invenzo tion. Fig. 2 is a view in plan with the parts above the bed-plate removed. Fig. 3 isafview of the bar F and its connections. -Fig. 4 is ,a similar view of the bar H. Fig. 5 is aview of the button. Fig.'6'is a view of the button-holder'D, showing its connection with the presser-foot. Figa- 7 is a ycross-section on the' dotted line 7 7- of Fig. 2. Fig. 8 isa' view 0f the end of the bar H. Figs. 9, 10, 1l, 12, and 13 are views showing diiferent ways of arranging the thread in sewing buttons.

Our invention is represented as applied to the machine known asthe Standard sewing-machine. It has a head A and a horn or cylinder B similar tothose ofthe said Stand-i ard machine, the horn or cylinder, however, being widened near. the point of its attach-f' ment tothe bed B' to provide room for a portion of the operating mechanism hereinafter described.4 The mechanism for performing 4o the stitch, Aincluding the needle, take up, shuttle, andfshuttle-'operating devices, are likethose of the saidStandard machine. The fabric to which the button is secured issupported vby a feed-plate ,Owhich -is provided Ywith lateral and forwardfand-backward move? mentsi relation to the stitching mechanism,-l

It will be understood, of course, that the work-support has in it ahole c of a size to attached to the arm D -inclnde the holes of the button. lt will be seen that the cam e' and the connecting de"A vices described provide the work -support with lateral movements or movements crosswise the usual line of feed and that there is also provided means by wl ,ich movements in the direction ofthe usualine offeed and at ro right angles to the length of the bar or horn may be provided the work-support. The devices for providing the work-support with this movement are shown in detail in Figs. 3 and 4, and they consist of a disk or short shaft G,

I5 mounted'n the cross-bar g of the horn, hav- `ing extended across its upper face a guideway g', in which is a sliding block g2, attached to the under surface of the work-holder bar F. This disk or shaft is adapted to be turned zo to cause this guideway to occupy any desired position-that is, it may be in line with 'the center' of the said bar F, when it will serve to steady the movements of said bar; but it will impart to the said bar no side movement, the

bar then moving may be moved to an angle from this mean line to one side or the other of it, and this position of the guideway will cause an oblique movement to be given to the bar F whensaid 3o bars moved longitudinally,and consequently alateral movement or a movement transverse to the usual direction of the feed will be im'- parted to the work-holder C, andthe extent of this lateral movement of the said workholder will vary according to-the length of the longitudinal movement 'of the said bar.

It will be understood that these-movements are imparted to the bar F because as the said bar is moved longitudinally, being piv- 40 oted au its inner end, the gnideway will cause itsoutcr end to be moved in one direction or the other, according as the gnideway .is turned. The position of the guideway is govcrnedby the cam c, with lwhich it is connected by the slide-bar II, the said bar having the cani-pin h,which enters the cam-groove e, and a forked end 7t,which straddles the stud c2, which thus acts to hold that end of the bar. The outer end of the bar is connected with the shaft or diskl G by the pin h2, which is at a right angle to lthe guideway formed therein and which has a block 7L.3,'which is received by the recess or pocket h* in the bar ll, the forward end of the slide-bar H sliding in the slideway h in the cross-bar g and beneath the swiveling-disk or shaft. The extent of movement of the slide-bar H governs the angle of the guideway r/ and may be varied to any extent by varying the camgroove c, and the cam-groove of course fixes the time of the change in the angle of the guideway. lt will be understood, of course, `that itis movable so as to throw the workholding plate either to one side or the other side of the central line of the horn and at any `desired time in respect to the time of the lat'- eral movement. The button-holdel-D is given longitudinally only, or it i and two intersecting or crossing bars.

the movements of the work-holder by being at d, the arm preferably curving upwardly and extending backwardly and downwardly to the pointf6,where itis attached to thebar F. The button-holder is attached to the arm D in a manner to per- -mit it to be moved vertically in relation to its end by means of the long pin d2, which extends from lthe block d? through a hole in said end d. This block carries the button-holder D, which .is inthe form of a plate having an extension en tering a recess or groove in said block and secured therein by a screw or any other desired way so as to be movable and removable. This block d3 is connected With a bracket d4,rigidly secured to the usual presserbar. This bracket is connected with the block d3 by the connection d5 in a manner to impart the downward movement of the presser-bar to the button-holdingplate D and'yet permit of the universal horizontal movement of the f button-hold er plate in relation to the presserbar. The tension or pressure on the button and fabric is controlled by the usual spring and nut of ,the Standard presser-bar, and the bar may be operated by the usual lift.

In use the button and the fabric upon which it is to be sewed are both clamped between the cloth-plate C and the button-holder plate D, and upon the starting of the machine a zigzag or hour-glass stitch, like'that shown in Fig. 13, will be sewed through the holes of.

the buttons, according as the work-plate and button-holder are moved by their operatingcams and controlling devices. If the swiveling disk is made inoperative by changing the location of the block h3 from the short recess or pocket h4 to the long recess or pocket h6 of the bar H, a stitch known as the single-bar stitch will be sewed. By the use of a pair of needles mounted upon the needle-bar so that a straight line passing through both'their eeuters would be at right angles tothe line of the shaft and giving the holder-plate and button-plate the lateral movement only last described a double-bar stitch would be sewed through the button in half the time usually required for making this stitch.

Any suitable starting and stopping device for permitting apredetermined number of stitches may be used upon' the machine.

It will be understood that the machine ernploys two threads, and that in the making of the hour-glass stitch, so-called, the transfer of the button is such and theinterloeking of the threads-that a knot is formed at ,the end of each full stitch. In other words, the

. threads fastening the buttousto t-he material are knotted as many times as they repeat the full stitch. glass stitch is made up of the bars which are at a right angle to the Wale of the garment This forms a stitcl1.made by two threads and very securely fastens the button to the fabric.

It will be seen that if the lateral movement takes place while the disk G is at rest an IOO It will be seen that the hourthe arm D',

oblique stitch is laid; butif the disk.G 0scil-V lates while the bar F is at rest a straight fori will be laid, and if low or tubular articles by stltches passing alternately through diiferent holes of such uttons, as will'be readily understoodI by those skilled in the art to which our inventionl relates. Also by connecting the movable button-holderD to the forward end of which from its tion with its operating-slidef6 extends npward and then forward and then downward to its point ofconnection with Having thus fully described we claim and desire to secure ent of the United States` In a machine for sewing on buttons, the combination with a stitch-forming mechana movable workesnpport and a movable our in vent-ion, by Letters Pat-- normally-stapivoted or swiveling device or disk, provided with a guideway, a pin or slide working in and longitudinally of said guideor periodically turning said pivoted device or -disk to cause tionary, pivoted as G 'working in and way at each ment of the said work-support holder, induced by said guideway, to be changed.
